HENRY C. BENWITZ, OF CHICAGO, ILLINOIS.

RGULaTING-VALVE.

To all 'whom 'it may concern:

Be it known that I, HENRY C. BENwrrz, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of lllinols, have invented a new and Improved Regulating-Valve, of which the following is a full, clear, and exact description.

This invention'is an improvement in regulating valves for the hot and cold water supplies leading to wash stands, bath tubsl and other similar places.

The invention has in view the provision of a valve including an actuating-lever or handle which is operable not only to control both the hot and cold water supplies, .but also control the waste or outlet.

The invention' further resides in certain special features of construction and combination of parts as will be hereinafter particularly set forth and claimed.

Reference is to be 'had to the accompanying drawings forming a p'art of this specification, in whichy similar characters of reference indicate corresponding parts in all the views.

Figure 1shows inside elevation partly in central section, my improved valve applied to a bath tub; Fig. 2 is a cross-section of the valve on the line 2-2 of Fig. 3 on an enlarged scale; Fig. 3 is a vertical section of the valve on the line 3-3 of Fig. 4; Fig. 4

is applan of the valve; Fig. 5 is a vertical section of the same on the line 5 5 of Fig. 4; and Fig. 6 is a cross section on the line (be of Fig. 5.

The casing proper of the valve comprises opp'ositely-disposed valve casings 10, and an intermediate expanded casing 11, the intermediate casing having a. chamber 12, which is surrounded by an annular passage 13 and connects at' its lower reduced end with an outlet pipe 14, forming, when t-he valve is applied, a continuation ofthe waste pipe 15, leading to the sewer.

The valve casings 1() have inlet connections 16 for the attachment of the hot and ycold water supplies, and oppositely-disposed Specification of Lettera Patent. Application filed January 7, 1908. Serial No. 409,648.

` Patented July 20, 1909.

' annular passage 13 through suitable openinvs 2() formed in the cylinder near ,the valve-head. The cylinder 18, as clearly shown in Figs. 2 and 3, seats in a depression in the side of the casing 11 when the plug 19 is screwed to place, and the said plug is recessed for receivinl a spring interposed between it and the va ve head, and provided with a bore22 of reduced diameter for receiving and forming a guide for the valvestem 23, the said stem passing through the annular passage 1'3 and `through the inner wall thereof` m-to the chamber 12. The valve-head 17 is preferably provided with a rubber or other elastic seating-face 24, to 'insure a watertight joint between it and the casing 11 when the valve is closed.

The casing 11 is provided with a removable cap 25 covering the chamber 12, and through the center of which is slidably splined by a key 26, a thimble 27, the key end, as best shown in Fig. 4, which is pivf otally attached at j diametrically opposite points to the head of a stud 32, the body of the stud having a projection 33, which, in connection with said body, is adapted to be passed into a slotted recess in the top of a pin 34, and when so inserted, the projection 33 may be engaged in an annular groove 35 in the recess of the pin, and prevent the disengagement of the stud from the pin until the projection is again brought into register with the longitudinal groove.

The lower portion ofthe thimble 27 is threaded or otherwise suitably fixed to a conical cam 36 located within the chamber 12, and against which the valve-stems 23 bear. The pin 34 passes through this cam, and is fixed within a spider which is ri 'd with the casing 11. The cylinder 37 is s idably mounted within the neck of the casing 11 and in the outlet pipe 14, and is normally pressed upwardly, tending to elevate the cam and attached mechanism, by a spring 37a. In order that the cylinder may pass above the spider, in which the pin 34 is through the intermediary of spiders so thata continuous passage is provided between the chamber 12 and the waste pipe 15, which will admit the ow of such water as leaks into the chamber around the valve-stems 23,

f ldirectly to the sewer.

The annular chamber 13 has a suitable outlet connection 41, which is designed to be piped to the bath tub, bowl or other similar device, (a bathtub being shown in Fig. l) the supply pipe 42 leading from said connection into this tub near its bottom. The connections 16 are coupled ywith the hoty and cold water supplies respectively, and the connection 40 1s connected with the outlet of the bath tub by a suitable discharge pipe 43. The overiow of the bath tub also connects with the outlet pipe 14 throu h a pipe 44. With the valve thus installed, on depressing the hand lever 31, both of the valves 17 will be fully opened by the cam 36.'

Simultaneously with the depression of the lever, the cylindrical valve 38 cuts off the communication between the discharge pipe 43 and the waste pipe, and on the revolution of the cam, the parts are locked against the action of the spring by the rojection 26. The operator may \then revo ve the handlever in either direction until water of the desired temperature is obtained. In order that this may be approximately determined, by observing the relative position of the handle, I graduate the cap 25, as illustrated in Fig. 4. By revolving the cam to the position shown in Fi 2, or to a reversed position, only one of t ie valves is opened. When the' water in the tub or other receptacle reaches the overflow pipe 44, it will pass \therethrough and through the outlet pipe 14 and waste pipe 15 to the sewer. The water isv cut off by again revolving the hand-lever until the projection 26 registers with the longitudinal groove in the thimble 27, at which time the spring 37 i automatically returns the cam and attached parts to the elevated position illustrated in Fig. 3, jand' simultaneously therewith opens the assage between the discharge pipe 43l an -waste pipe 15, and allows the watervto flow from the tub.

The invention as shown and described eessa valve controlling the communication between the inlet and outlet havin a stem passing through the assa e into t e chamber, a-waste pipe lea ing rom the chamber and having an opening, a valve movable over the opening in the Waste pipe, and means within the chamber and waste pipe`for respectively actuating said valve stem and the waste pipe valve.
